The "Zend Framework 101" series continues on the PHPRiot.com blog with this new look at the Zend_Registry component.

In this article in the Zend Framework 101 series I will introduce you to the Zend_Registry class. This class used is to allow you manage variables and objects in the global application namespace. This is used as an alternative to using global variables in PHP. I will show you how to use the Zend_Registry class and also provide a practical example of where it would be useful to use the registry.

You'll need a copy of the framework already up and working to follow along (no installation support here). His "real life" example - a quick fifteen lines of code - shows how to pull a Zend_Db database instances back out of a Zend_Registry object.
